Yes, that is the best idea, I think. What I don't like with the GUC
variable is, that it is _one_ warninglevel for all tablespaces
independent of their character. If I have two tables in different
tablespaces both with the global 90 percent threshold I may become
warned that tablespace A is 90 percent full, but if this tbsp. will only
grow one percent per day I still have 10 days left. Otherwise if I have
a tablespace B with 9 percent full but 5 percent growth per day that
will only be two days. So normaly id would have been fine to be warned 3
days ago for tablespace B but 5 "to early" for tablespace A.
Did you get the idea?
